LP2982AIM5X-3.0 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input supply pin; use a capacitor of 1 µF or larger from this pin to ground, and the new chip accepts 2.5 V to 16 V with an 18 V absolute maximum continuous input. |
| 2 | GND | power_in | Ground pin for the LDO. |
| 3 | ON/OFF | input | Enable pin: driving it high enables the device and driving it low disables it, with thresholds given in the Electrical Characteristics table; tie to VIN if unused, and the absolute maximum voltage is -0.3 V to 18 V for the new chip. |
| 4 | BYPASS | bidirectional | Bypass pin for low-noise performance; an external capacitor between BYPASS and ground reduces reference voltage noise (datasheet cites 30 µVRMS output noise with a 10 nF bypass capacitor). |
| 5 | VOUT | power_out | Regulator output; use a capacitor of 2.2 µF or larger from this pin to ground, and the nominal output capacitance for the new chip must exceed 2.2 µF with effective capacitance at the pin above 1 µF after derating. |
